For best results, 4-ANDRO should be used as part of a structured Andro cycle and followed with proper post-cycle support. Choose your stack based on your goal, experience level, and training phase.
4-ANDRO is Steel’s fullness, drive, and strength-support Andro, built for experienced lifters who want stronger training output, better cycle balance, and a fuller look during mass and performance-focused phases. Powered by 65 mg of 4-DHEA per tablet, also known as 4-Dehydroepiandrosterone, 4-ANDRO delivers 130 mg of 4-DHEA daily when used as directed and is designed to support the testosterone-pathway side of a structured Andro cycle.
Where 1-ANDRO is built for dry lean mass, density, and hardness, 4-ANDRO is built for fullness, drive, strength, and overall cycle support. It is one of the most important stack partners in the Steel Andro system because it helps round out cycles that may otherwise feel too dry, too flat, or too one-dimensional.
| Parameter | Specification |

| Amount Per Tablet | 65 mg |
| Recommended Daily Use | 2 tablets daily (130 mg daily active total) |
| Bottle Count / Supply | 60 tablets (30-day cycle supply when used as directed) |
| Formula Type | Non-methylated Andro support with Liposomal Delivery Technology |
| Primary Lane | Fullness, drive, strength, and testosterone-pathway cycle support |
| Best For | Lifters chasing fuller training output, size support, strength, and a more complete Andro cycle |
4-ANDRO is not the driest Andro in the Steel lineup, and that is exactly the point. Its role is to support the fullness, drive, strength, and balance side of a structured cycle. For users stacking drier Andros like 1-ANDRO, 3-EPI-ANDRO, or 7,3-ANDRO, 4-ANDRO can help create a fuller, more complete cycle experience.
This makes 4-ANDRO one of the most useful foundation products in the Steel Andro system. It is built for users who want more than a dry hardening effect. It is built for lifters who want to train harder, feel fuller, push heavier output, and support the overall strength-and-mass side of the equation.
4-ANDRO is designed for experienced lifters who want fullness, drive, and strength support during a structured Andro cycle. It is best suited for users focused on mass, strength, training performance, and cycle balance. If your goal is the driest, hardest cosmetic look possible, 3-EPI-ANDRO or 7,3-ANDRO may be a better primary fit. If your goal is fuller training output, strength, size support, and a more complete stack foundation, 4-ANDRO belongs in the conversation.
Every Steel Andro is built with liposomal delivery technology to help support absorption and ingredient uptake. By pairing active Andro compounds with lipid-based carriers, this delivery system is designed to improve efficiency compared to standard oral formulas.
For 4-ANDRO, that means each 65 mg tablet of 4-DHEA is delivered in a format built for serious users who care about consistency, precision, and performance-focused formulation.
Products: 4-ANDRO + 1-ANDRO
Best for users chasing lean size, strength, drive, fullness, and stronger training output.
Why this stack works: 1-ANDRO supports the dry lean-mass, strength, and density side of the cycle. 4-ANDRO supports fullness, drive, and the testosterone-pathway side. Together, this is the cleanest foundation stack for users who want lean mass and strength without feeling flat.
Best For: Lean mass, strength, muscular fullness, training drive, and more complete cycle support.
Products: 4-ANDRO + 19-NOR-ANDRO

Why this stack works: 1-ANDRO provides the lean-mass and strength base. 4-ANDRO supports fullness, drive, and cycle balance. 19-NOR-ANDRO supports strength, mass, recovery, and joint comfort during demanding training blocks. 17a-ANDRO adds advanced growth-phase support for users who want more cycle depth.
Best For: Highly experienced users, advanced mass-focused cycles, size and strength, muscular fullness, appetite support, recovery support, joint comfort during heavy training, and heavy-output performance.
Because 4-ANDRO is designed for structured cycle-based use, Steel recommends following your cycle with proper post-cycle support. Alpha-AF is Steel’s PCT and natural testosterone support formula, built with key minerals, hormone-support ingredients, and absorption support to help users transition after an Andro cycle.
Can Alpha-AF be used during a cycle? Alpha-AF may also be used by experienced users seeking additional hormone and mineral support during or after a cycle, but it is most commonly positioned as the post-cycle support product in the Steel system. If you are building a full Andro cycle, Alpha-AF should be considered part of the complete plan, not an afterthought.
ADABOLIC: Can be used alongside structured Andro cycles by users looking to
support training output, pumps, recovery, hydration, and performance during demanding training blocks. Best
paired with lean mass, strength, mass, and fullness-focused Andro stacks.
HYPERBOLIC: Best suited for users in a calorie-supported growth phase. It
pairs well with mass-focused stacks where the goal is size, fullness, recovery, and consistent daily nutrition.
Best paired with stacks like 4-ANDRO + 1-ANDRO, 4-ANDRO + 19-NOR-ANDRO, or 4-ANDRO + 1-ANDRO + 19-NOR-ANDRO.
Steel Andros are built for structured, goal-specific cycles. To get the most out of your cycle, support the process with disciplined training, nutrition, hydration, sleep, and post-cycle support.
During use, we recommend avoiding alcohol and unnecessary stressors that can work against recovery, hydration, sleep quality, liver health, hormone balance, and training performance. Users should not exceed the recommended daily use and should avoid combining multiple hormone-pathway products unless they are experienced and understand structured cycle-based supplementation.
For best results, pair your Andro cycle with consistent protein intake, goal-appropriate calories, progressive training, adequate rest, and proper post-cycle support with Alpha-AF.
For lean mass: Maintain a moderate calorie surplus with high protein intake,
consistent carbohydrates around training, and enough dietary fats to support hormone health and
recovery.
For mass-focused stacks: Prioritize total calories, protein, carbohydrates,
hydration, and recovery. 4-ANDRO is especially useful in stacks where fullness, drive, and size support are
priorities. Products like HYPERBOLIC can help users who struggle to consistently eat enough during growth
phases.
For cutting or recomposition: Use a controlled calorie deficit or maintenance
intake, keep protein high, and avoid crash dieting. If using 4-ANDRO during a recomp phase, the goal is to
support fullness, output, and performance while body composition improves.
For best results during an Andro cycle:
Advanced Stack Notice: More is not always better. Advanced stacks are intended for experienced users only. If you are new to Andros, start with a simpler cycle before combining multiple products. Users should choose a stack based on their goal, experience level, training status, and tolerance. Do not exceed recommended use.
Important Use Notice: Not for use by individuals under 18. Do not use if pregnant, nursing, or trying to become pregnant. Consult a qualified healthcare professional before use if you have or have had liver, kidney, cardiovascular, blood pressure, endocrine, prostate, cholesterol, or other medical concerns, or if you take prescription medications. Discontinue use and consult a healthcare professional if you experience adverse reactions.
Important Cycle Note: For maximum results, this product is designed to be used as part of a structured Andro cycle and followed with proper post-cycle support. Individual results may vary based on training, nutrition, consistency, experience level, and overall cycle structure.
Steel Andros are not casual daily wellness products. They are advanced performance supplements for experienced users who respect the process: train hard, eat with purpose, recover intelligently, avoid alcohol during use, and follow the cycle with proper post-cycle support.
For best results, 4-ANDRO should be used as part of a structured Andro cycle and followed with proper post-cycle support. Choose your stack based on your goal, experience level, and training phase.
